This is interesting. How to use CSCL environment to detect fading and how fading should occur. Maybe there is a way of measuring learners' skills and based on such assessment, adjust scaffolding accordingly. This could be done again by measuring learners' emotions, motivations, self reports and quizzes.

hese can include language and preferred communica-tion style as well as prior cultural–educational experiences which makes studentsfeel unprepared to break out of their comfort zone and interact with less familiarpeers

this is true. Some learners from certain cultures may not be as comfortable speaking up in a group. However, online interaction may serve as an advantage because those learners may feel less shy or nervous to share their opinions.

One draw back of computer based learning is that using a computer, or any devices really, can be quite distractive...Even when using this annotation software, I notice myself constantly getting distracted by emails and wanting to go on other websites. How can we design something that helps self regulation and reduce distraction?

Another thing is that not all users are comfortable or competent in using technology which could cause frustration and distract from learning. How can we reduce this?

This is so true. Sometimes not all group members get along with each other, especially if some people are being disrespectful, etc. How can we avoid this to achieve better group dynamic and better learning?

If emotions and motivations are so central to learning design, perhaps we could implement a way to measure learners' emotions during the learning process via computer. For example, we could use webcam to measure their facial expression and adapt learning according. If we detect that the students is frustrated, we could provide more support, etc.

Goal of reading the article:
think about 4-5 design principles you could extract from the text and that you as an instructor could use to design a computer-supported learning environment. Try to think about why these principles should be taken into account to facilitate learning.
